so the new line must be y = (-1/5)x + b
which automatically rules out a) and d)
plug in the point (-10,3) and find b to decide which of the remaining choices is it.
Which equation is the equation of a line that passes through (-10, 3) and is perpendicular to y=5x-7?
a. y=5x +53
b.y=-1/5 x -7
c. y=-1/5x+1
d. y=1/5x +5.
